Here are a couple of recent pictures of two of my goldfish. Zippy is a calico red cap oranda and Max is a matte pearlscale. Photos were taken in available light with a D50. If anybody wants more specific info, let me know and I'll get the EXIF data for you.

Those are beautiful fish and you sure know how to photograph them, not an easy task usually. If people don't keep fish they don't know how their personalities vary and how tame they can become, to the point of enjoying touching or cuddling in your hand, especially the fancy goldfish.
